General description

Goldenseal is a perennial herb. It’s native to North America. The roots and rhizome are the parts that are used.

Goldenseal contains the alkaloids hydrastine and berberine. These have weak antiseptic properties. These parts may help fight bacteria-induced diarrhea. You shouldn’t take goldenseal during pregnancy. This is because it may cause uterine contractions.

In the past, goldenseal was used by Native Americans to treat sore eyes, mouth ulcers, tuberculosis, and edema. Now, there’s evidence that berberine works against resistant strains of tuberculosis. However, berberine isn’t used as a primary or add-on treatment for tuberculosis.

Goldenseal has also been used as an eye-drop. It’s used on tired, burning, red, and irritated eyes.
